Metallized polymeric film reflective insulation material

Abstract

A method of thermally insulating an object that requires a Class A standard insulation material, said method comprising suitably locating a metallized polymeric reflective insulation material adjacent said object, wherein said polymeric material is selected from a closed cell foam, polyethylene foam, polypropylene foam, expanded polystyrene foam, multi-film layers assembly and a bubble-pack assembly. The object is preferably packaging, a vehicle or a residential, commercial or industrial building or establishment. The polymeric material may contain a fire-retardant and the bright surface of the metallized layer has a clear lacquer coating to provide anti-corrosion properties, and which maintains satisfactory reflectance commercial criteria.

1. A method of thermally insulating an object that requires a Class A standard insulation material having a flame speed rating value of 0 to 25 and a smoke developed rating value of 0 to 450, said method comprising
 suitably locating a reflective insulation material in a thermally insulating position adjacent to said object, 
 wherein said reflective insulation material comprises a bubble-pack assembly having a metallized polymeric film bonded thereto such that said metallized polymeric film is positioned to provide said assembly with a reflective metallized outer surface, said reflective metallized outer surface having a clear, anticorrosion lacquer protective coating thereon, 
 wherein said metallized polymeric film with the protective coating thereon has a surface thermal emissivity equivalent to or greater than 95% reflectance and 
 wherein said metallized polymeric film excludes a metal foil on a polymeric film, said insulation material being sufficient to satisfy the requirements for Class A thermal insulation. 
 
     
     
       2. A method as claimed in  claim 1  wherein said object is selected from an article to be packaged, a vehicle and a residential, commercial or industrial building or establishment. 
     
     
       3. A method as claimed in  claim 2  wherein said object is a residential, commercial or industrial building or establishment requiring Class A standard insulation material, said method comprising locating said reflective insulation material within a frame structure, wall, crawl space or ceiling, or wrapping water heaters, pipes or air ducts within said building or establishment. 
     
     
       4. A method as claimed in  claim 3  wherein said bubble-pack assembly comprises a first thermoplastic film having a plurality of portions wherein each of said portions defines a cavity; and a second film in sealed engagement with said first film to close each of said cavities. 
     
     
       5. A method as claimed in  claim 4  wherein said thermoplastic film is selected from the group consisting of low density polyethylene, linear low density polyethylene and nylon. 
     
     
       6. A method as claimed in  claim 4  wherein said thermoplastic film contains an amount of an added fire-retardant material effective to enhance the fire-retardant properties of the assembly. 
     
     
       7. A method as claimed in  claim 4  wherein said bubble-pack assembly further comprises at least one or a plurality of additional thermoplastic films. 
     
     
       8. A method as claimed in  claim 4  wherein said metallized polymeric film contains an amount of a fire-retardant additive effective to enhance the fire retardant properties of the assembly. 
     
     
       9. A method as claimed in  claim 1  wherein said metallized polymeric film comprises a metallized polyethylene or polyester film. 
     
     
       10. A method as claimed in  claim 9  wherein the metal in the metallized polymeric film is aluminum. 
     
     
       11. A method as claimed in  claim 1  wherein said metallized polymeric film comprises a fire-retardant material admixed with the polymer of said film. 
     
     
       12. A method as claimed in  claim 1  wherein said reflective insulation material is free from any added fire-retardant material and said metallized polymeric film is aluminized polyester film. 
     
     
       13. A method as claimed in  claim 1  wherein said lacquer protective coating comprises an acrylic polymer or copolymer of 80,000-150,000 molecular weight. 
     
     
       14. A method of thermally insulating an object that requires a Class A standard insulation material having a flame speed rating value of 0 to 25 and a smoke developed rating value of 0 to 450, said method comprising
 suitably locating a reflective insulation material in a thermally insulating position adjacent to said object, 
 wherein said reflective insulation material comprises a bubble-pack assembly having a metallized polymeric film bonded thereto such that said metallized polymeric film is positioned to provide said assembly with a reflective metallized outer surface, said reflective metallized outer surface having a clear, anticorrosion lacquer protective coating thereon, 
 wherein said metallized polymeric film with the protective coating thereon has a surface thermal emissivity equivalent to or greater than 95% reflectance, 
 wherein said metallized polymeric film excludes a metal foil on a polymeric film, 
 wherein said bubble-pack assembly comprises a first thermoplastic film having a plurality of portions wherein each of said portions defines a cavity; and a second film in sealed engagement with said first film to close each of said cavities, 
 wherein said metallized polymeric film comprises a metallized polyethylene or polyester film, 
 wherein said metal in the metallized polymeric film is aluminum and 
 wherein said thermoplastic film is selected from the group consisting of low density polyethylene, linear low density polyethylene and nylon, 
 said insulation material being sufficient to satisfy the requirements for Class A thermal insulation.
